On Windows 7 x64, Device Manager detect my modem as HDAUDIO Soft Data Fax Modem with SmartCP, I would like to know if I can connect the landline to my modem port, and when there is a call, grab the phone number?

I need to grab the Phone Number, so it can be used on a software I'm doing.

I want the phone number of the person calling me. I'm using Delphi as my development tool.

HyperTerminal ATZ - OK AT+VCID=1 - OK

  • What do you mean with grabbing the phone number? Do you want the phone number of the person calling you? – Hennes Dec 5 '13 at 14:29
  • This will only work with CLIP enabled. – Marcel Dec 5 '13 at 14:30
  • You should state which phone number you want to retrieve. The number of the called party or the number calling party? As for Caller Id and incoming calls +CLIP is for cellular modems. +VCID or #VCID is used for land lines. – jww Mar 14 at 2:53

This will only work if the caller has CLIP enabled.

Have a look here: http://www.activexperts.com/mmtoolkit/at/commands/?at=%2BCLIP where the describe the AT+CLIP - Calling line identification presentation command. This will most probably work with your modem too.

From This description

6) ATA - This command is used to answer a call. An incoming call is indicated by a message ‘RING’ which is repeated for every ring of the call. When the call ends ‘NO CARRIER’ is displayed on the screen. SYNTAX: ATA(Enter)

As ATA followed by enter key is pressed, incoming call is answered. For example,

RING
RING
ATA

I seem to remember some modems following RING with the incomming telephone number, when caller-id is enabled on the phone-line. For example :

RING 01206821212
